ARIA ONE

Hearing Personalization

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

ARIA ONE is a sound personalization app built from your unique hearing profile. Take the FullScale hearing test — a full-spectrum assessment mapping up to 37 frequencies per ear. Choose Instant, Quick Results, or Full Accuracy pathways. Complete a profile in as little as 8 minutes. Your hearing profile directly powers correction, limiter behavior, presets, and your personalized listening workflow. Three macro controls — Drive, Intensity, and Smoothing — shape the character of your sound. Three mood presets — Calm, Natural, and Intense — switch your full DSP state with a single tap. Play your own music library through your personalized DSP chain with the built-in audio player. ARIA AI gives you access to the full parameter space without touching a single knob. Describe what you want — "make the bass warmer," "tighten the transients," "reduce harshness" — and the AI adjusts one or many parameters at once across correction, dynamics, drive, and limiting. Choose Standard, Fine Tune, or Thinking agents depending on how broad or surgical you want the changes. Keep refining over time instead of learning the parameter space yourself. Presets, hearing profiles, and mood assignments sync across your devices. Use the Advanced View on Mac or Windows to fine-tune your sound with 400+ parameters, then push your presets and moods directly to your phone. Check out a mobile device remotely, dial in its settings from the full desktop interface, and commit changes back. On desktop, ARIA ONE is available as a standalone app and VST3/AUv3 plugin with eight graphing windows and ITU-R BS.1770 loudness metering. Part of the Altitude personalization ecosystem: FullScale, ARIA Studio, Absolute Zero, and Crossfeed.
